GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 591,427, dated October 12, 1897- A'ppnmion nea February 2,1897. serrano. 621,601. nu iwda.)

To all whom/it may concern:

Beit known that I, CHARLES B.ScHoEN MEHL, a citien of the United States, and a resident of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements vised the simple and novel construction shown in the accompanying drawings, and of Which- Figure l is a central vertical section. Fig. 2 is a detachedside vievs7 of my novel basket which constitutes the negative element of the battery. Fig. 3 is a sectional plan View of my battery, taken on line 3 3 of Fig. l. Fig. 4 is a detail side view of one of the insulating-blocks H, Which rest upon projections of the bottom and support the zinc ring. Fig. 5 is a detail plan view showing clearly the mannerin which the binding-wire is attached. Fig. 6 is a detail elevation of the parts shown in Fig. 5.

The same characters of reference denote like or corresponding parts upon the several figures of the drawings.

A indicates a common form of glass jar, such as is employed inlbatteries of this class.

B is a tin or porcelain cover for said jar, and to Which I attach a specially-formed perforated tin or similar sheet-metal basket C,

in which is introduced a quantity of oxid of copper, or similar depolarizing material. Said basket is provided with a series of corrugations D .upon its periphery, as shown in the several igures of the drawings. The object in corrugating the side Walls of the basket is to increase its exterior surface, thereby more readily exposing the contentsthereof in a I manner to more effectually act upon the posivket,and cover-rmly together. Said bottom,

as will be obvious, has its periphery cut to correspond with the peripheral corrugations in the basket, exceptat certain intervals, Where said bottom is carried across one of the concave surf aces of said corrugations forthe purpose of forming supports G for the special insulating-blocks I-I, which rest in said concaves and upon the projecting bottom. These .insulating-blocks II are preferably formed of porcelain and consist of a body portion whose shape on back practically corresponds with the concave in which it its, also a projection having a narrow top edge upon which the zinc ring I rests. Said ring forms the positive element of the battery and is provided with a Wire connection J, laid between the connecting ends of said zinc and soldered thereto, thereby securing a reliable, positive, and improved connection of the zinc and Wire.` The upper end of said wire passes through the cover4 and is provided with a bindingscrew K, as shown.

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Pat- 1. In aprimary batteryl of the class described, the combination of a jar provided With a cover, a basket forming an electrode attached to said cover and having a corrugated peripheral surface, a depolarizing material Within said basket, projections upon the bottom of saidbasket, insulating-blocks adapted to lit upon said projections and to supporta zinc, a zinc encircling said basket and having a binding-screw connection.

2.. In a galvanic battery of the class described, the combination of the jar, a cover fitted thereto, a perforated corrugated conducting-basket containing a suitable depolarizin g material, bolts passing through said basprovided with a conducting-wire scoured between the adjacent Vertical edges of said zinc, substantially as described.

Signed at Bridgeport, in the county of Fair- I 5 field and State of Connecticut, this 25th day of January, A. D. 1397.
